Examples provided by Insure++
Log onto a SLAC Unix machine of a supported architecture. Set up your environment as described above, and locate the examples in
the directory $INSURE/examples/cpp. Copy leak.C to a directory where you have write privilege. Compile and link it using the
insight command, and run it. Also try other examples.
$ cd mytest
$ cp $INSURE/examples/cpp/leak.C .
